1. A method of routing, by a user plane entity (UPE), the method comprising:
receiving an initial data packet using a shared user plane (UP) tunnel, the initial data packet included in a tunneled data packet; and
selecting a user plane connection based on traffic differentiation information (TDI) included in a tunnel header of the tunneled data packet, the TDI differentiating the initial data packet from other traffic using the shared UP tunnel, the TDI comprising one or more of:
an identifier (ID) of a PDU session associated with the initial data packet,
destination information indicating a destination of the initial data packet, and an ID of a UP path indicating the UP path over which the initial data packet is being routed; and
routing the initial data packet according to the user plane connection.
